Is it COVID-19? Flu? At-home rapid tests could help you and your doctor decide on a treatment plan
At-home rapid tests for COVID-19 and influenza are becoming available, allowing simultaneous diagnosis, which aids timely and effective treatment and improves patient outcomes.

A scratchy, sore throat, a relentless fever, a pounding head and a nasty cough – these symptoms all scream upper respiratory illness. But which one?
Many of the viruses that cause upper respiratory infections such as influenza A or B and the virus that causes COVID-19 all employ similar tactics. They target the same areas in your body – primarily the upper and lower airways – and this shared battleground triggers a similar response from your immune system. Overlapping symptoms – fever, cough, fatigue, aches and pains – make it difficult to determine what may be the underlying cause.
Now, at-home rapid tests can simultaneously determine whether someone has COVID-19 or the flu. Thanks in part to the National Institutes of Health’s Rapid Acceleration of Diagnostics, or RADx, program, the Food and Drug Administration has provided emergency use authorization for seven at-home rapid tests that can distinguish between COVID-19, influenza A and influenza B.
Our team in Atlanta – composed of biomedical engineers, clinicians and researchers at Emory University, Children’s Healthcare of Atlanta and Georgia Institute of Technology – is part of the RADx Test Verification Core. We closely collaborate with other institutions and agencies to determine whether and how well COVID-19 and influenza diagnostics work, effectively testing the tests. Our center has worked with almost every COVID and flu diagnostic on the market, and our data helped inform the instructions you might see in many of the home test kits on the market.
While no test is perfect, to now be able to test for certain viruses at home when symptoms begin can help patients and their doctors come up with appropriate care plans sooner.
A new era of at-home tests
Traditionally, identifying the virus causing upper respiratory illness symptoms required going to a clinic or hospital for a trained medical professional to collect a nasopharyngeal sample. This involves inserting a long, fiber-tipped swab that looks like a skinny Q-tip into one of your nostrils and all the way to the back of your nose and throat to collect virus-containing secretions. The sample is then typically sent to a lab for analysis, which could take hours to days for results.
Thanks to the COVID-19 pandemic, the possibility of using over-the-counter tests to diagnose respiratory illnesses at home became a reality. These tests used a much gentler and less invasive nasal swab and could also be done by anyone, anytime and in their own home. However, these tests were designed to diagnose only COVID-19 and could not distinguish between other types of illnesses.
Since then, researchers have developed over-the-counter multiplex tests that can screen for more than one respiratory infection at once. In 2023, Pfizer’s Lucira test became the first at-home diagnostic test for both COVID-19 and influenza to gain emergency use authorization.
What are multiplex rapid tests?
There are two primary forms of at-home COVID-19 and COVID-19/flu combination tests: molecular tests such as PCR that detect genetic material from the virus, and antigen tests – commonly referred to as rapid tests – that detect proteins called antigens from the virus.
The majority of over-the-counter COVID-19 and COVID-19/flu tests on the market are antigen tests. They detect the presence of antigens in your nasal secretions that act as a biological signature for a specific virus. If viral antigens are present, that means you’re likely infected. https://www.youtube.com/embed/s45GMoZaHFE?wmode=transparent&start=0 Respiratory illnesses such as flu, COVID-19 and RSV can be hard to tell apart.
To detect these antigens, rapid tests have paper-like strips coated with specially engineered antibodies that function like a molecular Velcro, sticking only to a specific antigen. Scientists design and manufacture specialized strips to recognize specific viral antigens, like those belonging to influenza A, influenza B or the virus that causes COVID-19.
The antibodies for these viral targets are placed on the strip, and when someone’s nasal sample has viral proteins that are applied to the test strip, a line will appear for that virus in particular.
Advancing rapid antigen tests
Like all technologies, rapid antigen tests have limitations.
Compared with lab-based PCR tests that can detect the presence of small amounts of pathogen by amplifying them, antigen tests are typically less sensitive than PCR and could miss an infection in some cases.
All at-home COVID-19 and COVID-19/flu antigen tests are authorized for repeat use. This means if someone is experiencing symptoms – or has been exposed to someone with COVID-19 but is not experiencing symptoms – and has a negative result for their first test, they should retest 48 hours later.
Another limitation to rapid antigen tests is that currently they are designed to test only for COVID-19, influenza A and influenza B. Currently available over-the-counter tests aren’t able to detect illnesses from pathogens that look like these viruses and cause similar symptoms, such as adenovirus or strep.
Because multiplex texts can detect several different viruses, they can also produce findings that are more complex to interpret than tests for single viruses. This may increase the risk of a patient incorrectly interpreting their results, misreading one infection for another.
Researchers are actively developing even more sophisticated tests that are more sensitive and can simultaneously screen for a wider range of viruses or even bacterial infections. Scientists are also examining the potential of using saliva samples in tests for bacterial or viral infections.
Additionally, scientists are exploring integrating multiplex tests with smartphones for rapid at-home diagnosis and reporting to health care providers. This may increase the accessibility of these tests for people with vision impairment, low dexterity or other challenges with conducting and interpreting at-home tests.
Faster and more accurate diagnoses lead to more targeted and effective treatment plans, potentially reducing unnecessary antibiotic use and improving patient outcomes. The ability to rapidly identify and track outbreaks can also empower public health officials to better mitigate the spread of infectious diseases.

Millions of mobile gamers prize stress relief over winning
Mobile Gamers Prize Stress: In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
Millions of mobile gamers prize stress relief over winning
(Sheeka Sanahori) In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
According to a June 2026 survey of more than 128,000 KashKick mobile gamers, playing a mobile game is more than a way to pass the time. Stress relief and relaxation are the top reasons respondents play, beating out entertainment and fun. As KashKick reports, for many people, this means mobile games are less a simple distraction and more a coping mechanism for the daily stress of life.
A quick reset for life’s transitional moments
Most respondents identify as women, and 60% live in households that earn less than $50,000 per year. In the ranking of their reasons for playing, stress relief and relaxation topped the list, with boredom relief, entertainment and fun close behind.
The ranking reads less like a profile of a gaming hobby and more like a profile of a coping behavior.
More than half of the respondents play games daily or multiple times a day. When they reach for a mobile game, about 53% of the time it’s for a short session—usually 30 minutes or less. Where and when people play tells its own story: 58% play in bed before going to sleep and 40% play in the bathroom. These are private, solitary moments, not the times people typically plan entertainment into their day.
Coping with stress by gaming
To understand why respondents play games for stress relief more than for fun, it helps to look at who they are. Among those surveyed, 19% say they’re unemployed or looking for work, and 60% live in lower-income households. There are likely some areas of their life where they must make every dollar stretch to cover the things they need.
The survey findings coincide with research from the American Psychological Association’s 2025 Stress in America report. According to the report, 18% of men and 22% of women under age 65 rate their stress level at eight or higher on a scale of one to 10. Although the KashKick survey didn’t measure stress, respondents are mostly women and fall within the age and income groups the APA found to carry the most stress.
The APA’s report also describes loneliness as a major strain for Americans. The KashKick survey didn’t measure feelings of isolation, but 55% prefer to play alone, and 60% rarely or never discuss their gameplay with friends or family.
Overall, the survey identifies a group of people who have found a routine, low-cost approach to cope with stress. They’re not necessarily there to get the highest score. They’re playing a mobile game to help them navigate a day that, with all of life’s to-dos and challenges, could quickly feel overwhelming.
Methodology
The KashKick Gaming Habits Survey was fielded from June 8, 2026, through Aug. 10, 2026, among KashKick members in the United States who play mobile games. The Gaming Habits Survey was available to all members on KashKick’s Surveys page post-profile completion. The survey received 128,218 total responses, with question-level response counts ranging from approximately 109,793 to 128,218 depending on attrition. All findings describe KashKick mobile gamers and should not be interpreted as representative of U.S. mobile gamers overall. Industry and stress context references publicly available data from the American Psychological Association, Statista, and Newzoo.

Covering Basic Expenses with Credit Cards Adds to the Growing Debt Cycle
The Debt Cycle: For many Americans, credit cards were once reserved for emergencies, major purchases or added security when shopping online. However, today, people are increasingly relying on credit cards and unsecured debt to cover basic everyday expenses like groceries.
Covering Basic Expenses with Credit Cards Adds to the Growing Debt Cycle
(Feature Impact) For many Americans, credit cards were once reserved for emergencies, major purchases or added security when shopping online. However, today, people are increasingly relying on credit cards and unsecured debt to cover basic everyday expenses like groceries.
According to a survey of 2,000 U.S. adults with at least $10,000 in unsecured debt conducted by Atomik Research on behalf of Accredited Debt Relief, a debt consolidation company specializing in unsecured debt relief, credit cards are no longer just a financial convenience but a tool for managing the rising cost of everyday necessities.
In fact, 66% of respondents reported having used a credit card to cover the cost of groceries within the last year. Other essentials aren’t far behind: 47% said they’ve used it for gas or transportation, 45% for utilities and 33% for rent or housing costs.
How Everyday Expenses Turn into Long-Term Debt
Debt builds over time when credit becomes part of monthly operations. For those struggling with cost-of-living pressures, using a credit card to cover groceries or utility bills may seem manageable in the moment. When the unexpected happens – a car repair, medical bill or unusually high energy bill – however, the balance adds up for the 46% of respondents who take on additional debt at least most of the time an emergency occurs and, without an executable plan for repaying it, could shorten the runway for taking care of such expenses in the future.
Because nearly 3 in 10 survey respondents rely on credit or borrowing just to get through a typical month, the data suggests what may have been a stopgap has become a routine part of managing personal finances. In fact, one-third of survey respondents said they depend on credit more than they did a year ago.
Lack of a Financial Cushion Makes Paying Down Debt Difficult
Breaking the debt cycle becomes especially difficult without emergency savings. Only 28% of respondents say they can cover expenses and save.
Additionally, 45% reported their income is enough to get by but not get ahead. Many said they’ve even put off taking a vacation or saving for the future due to their financial situations. When each paycheck is already committed to existing bills – 29% of respondents listed the cost of everyday expenses as the biggest barrier to reducing debt – making meaningful progress toward paying down debts becomes more difficult.
The Emotional Cost of Carrying Debt
Financial stress affects more than just the household budget. The survey found 25% of respondents are concerned about their financial future, with 12% worried they’re facing long-term financial instability. What’s more, nearly 7 in 10 said their current debt situation has negatively affected their mental well-being.
Without meaningful changes, whether through increased income, debt relief or financial support, these households may continue to rely on unsecured credit as a necessity rather than a strategic financial tool or occasional supplement.

ABCs for School Zone Safety: Tips for Drivers, Pedestrians and Bicyclists
School Zone Safety: A new school year means there’s more traffic around school campuses. Between dropoffs and pickups, children riding bicycles, walking to school and all the shuttling between sports practices and other extracurricular activities, this season is a reminder to make every trip to and from school a safe one.
ABCs for School Zone Safety: Tips for Drivers, Pedestrians and Bicyclists
(Feature Impact) A new school year means there’s more traffic around school campuses. Between dropoffs and pickups, children riding bicycles, walking to school and all the shuttling between sports practices and other extracurricular activities, this season is a reminder to make every trip to and from school a safe one.
To make sure no parent worries about their child getting to school safely, the California Office of Traffic Safety (OTS) and Caltrans are encouraging drivers, pedestrians and bicyclists to remember their “ABCs” on every trip: stay Alert for Bicyclists and watch for and yield to Children crossing the street.
With students in school and traffic patterns changing, consider these tips so students arrive to and from class safely:
Drivers
Because children outside of vehicles do not have the same protections as drivers and passengers, drivers have an outsized role to protect people walking, biking and rolling.
- Take your time and be patient.
- Always follow the speed limit.
- Use extra caution at crosswalks and intersections, especially if you notice children nearby.
- Don’t drive distracted – even a quick glance at your phone can have tragic consequences.
- Never drive while impaired.
- Adjust your driving to the conditions and use extra caution in rain, fog and darkness.
- If you see a bicyclist ahead, wait until it’s safe to pass and give them at least 3 feet of space when you do.
Pedestrians
Pedestrians have an important role in their own safety, particularly in school zones and crosswalks where children and other people may be present.
- Use sidewalks when available. If there are no sidewalks, walk facing traffic so you can see drivers and they can see you.
- Avoid crossing outside of crosswalks. If there is a signalized crosswalk or marked crosswalk, use it.
- Before crossing the street, look both ways. If there are any stopped or turning cars, try to make eye contact with the drivers before crossing so you know they see you.
- If you’re walking after dark or when visibility is poor, make yourself visible by wearing something bright or reflective and shining a light.
- Stay alert – don’t wear headphones or use your phone while crossing the street or walking across a busy road.
Bicyclists
Bicyclists can help protect themselves by staying alert and visible, especially in areas where traffic, pedestrians and young students may be present.
- When possible, plan your route along bike paths or roads with dedicated bike lanes away from vehicle traffic.
- Equip your bicycle with lights and reflectors to be more visible to drivers and pedestrians.
- Wear a properly fitted helmet and bright clothing.
- Learn cyclist hand signals to communicate when you’re turning, slowing or stopping.
- Stay aware of drivers and always yield to pedestrians.

E-Bike Safety Tips
With more young people using e-bikes than ever before, it’s important that riders and their parents or guardians understand the risks involved and make smart, safe choices.
Since e-bikes can travel at faster speeds than traditional bicycles, they pose greater risk for serious injury or death in the event of a crash. Class 1 and 2 e-bikes can both travel at up to 20 mph unassisted, while Class 3 e-bikes can go as fast as 28 mph unassisted.
E-bike rules vary based on the top unassisted speed, but parents and guardians should follow these tips for e-bikes:
- Many local ordinances and state laws restrict e-bike use for minors or require special licensing.
- Helmets are required for riders under age 18 for Class 1-2 e-bikes and all riders on Class 3 e-bikes, regardless of age.
- You must be 16 years or older to ride a Class 3 e-bike.
- Never ride e-bikes that don’t have pedals as they could be considered e-motos and not legally permitted on roads.
- Ride in bike lanes or on legal paths, avoiding roads with traffic when possible.
- Be as predictable as possible and use caution when making turns, crossing streets or riding in conditions with poor visibility.
E-bike rules may vary by state and regionally. Contact local law enforcement regarding local laws.
